12) Look at table 2. Which unit was the quietest on (2pts) average? 13) Look at table 2. Where, on average, was the noisiest location on the (2pts) units? 14) Look at table 2. Were patient interactions or employee interactions (2pts) louder? 15) Look at table 5. Pearson correlation coefficients were calculated to determine the association (3pts) between heart rate and noise level (sound pressure level). What do you know about the overall correlation between these two variables in this sample? Verdana 11 pt BI! A A 0 WORDS 16) The researchers indicate that significant positive correlations were found between heart rate and (4pts) noise levels in patients rooms, communicating with staff and between patients and their families and during all nursing activities. They explain that direct care may be a confounding factor for this finding. Explain what this means in your own words
